BMW i3s traction control tech going in all BMW, Mini cars

The BMW i3s is essentially a warmed-up version of the i3 electric car we all know and love. The performance boost isn't huge — just 14 horsepower and 15 pound-feet of torque — but it also gets a new suspension, wheels and tires as well as an improved traction control system. We found the car to benefit from all the updates when we drove it for our First Drive Review, but now BMW has offered up more details on just how the traction control system of the i3s helps make it better to drive. The company says it'll expand the technology to all future BMW and Mini models as well. The i3s's system is calibrated to help it to pull away quickly from a stop, making full use of the instantaneous torque offered by the electric motor. It also improves stability when accelerating out of corners, when using regenerative braking and, of course, when the road conditions are less than ideal. The results are palpable, and with the other improvements the i3s definitely feels stronger off the line, as we found on our drive. It's also about a half-second quicker to 60 miles per hour, at 6.8 seconds. The secret is in the response time of the stability control, which BMW claims is 50 times faster than the conventional system. This is made possible by moving the control process into the powertrain itself, rather than a remote unit. This reduces the signal path and, thus, the response time of the traction control system. BMW's Head of Chassis Development, Peter Langen, said of it, "With their high levels of torque and instantaneous responses to every movement of the accelerator, electric motors already make significantly higher demands on driving stability systems than conventional power units." While engineered to make the most of the electric motor, BMW says the shorter cycles of this traction control system show promise for internal combustion vehicles as well. As such, we'll begin to see the improved technology applied across the BMW and Mini lineups going forward. Related Video:

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.

Best electric sedans of 2024

While the American automotive trends tend to lean toward SUVs and trucks, and sedans seem to be dying out, there are some great four-doors out there in the EV market. They may not have the bulk, the high vantage point, or the storage capacity of the utes, but some folks still want a car that’s, well, a car. A sedan might not always have as much room to cram in a big battery pack, either, but they also donÂ’t weigh as much. They tend to be more lithe, sexy and agile. And theyÂ’re generally cheaper than their bigger brethren, too, though some of the full-size luxury sedans can still get well into six-figure pricing. If thatÂ’s not your thing, you can check out the best electric SUVs, but if youÂ’ve read this far, you probably enjoy sedans as much as us. WeÂ’ve tested quite a few, and these are the best electric sedans of 2024.   Best electric sedans below $60,000 Tesla Model 3 — $40,380 The Tesla Model 3 is one of just two sedans (along with the Hyundai Ioniq 6) to make it onto our list of best EVs under $50,000. ItÂ’s quite the value, too, with a starting price of just $40,380. ItÂ’s also fun to drive. Yes, it has some quirks, including too many vehicle functions residing exclusively in infotainment menus, but the Model 3's idiosyncrasies are easy to forgive based on its price and range, and they're things you can quickly get used to or possibly even appreciate. No wonder this EV is so popular.   Hyundai Ioniq 6 — $43,565 Of the sedans on this list, the Ioniq 6 is one of the most affordable (starting at $43,565), and one of the best. ItÂ’s quite efficient, with long driving range — up to 361 miles. Its cabin is creative in its design while being practical and comfortable. Interestingly, the Hyundai Ioniq 6 is the sportiest version of Hyundai and KiaÂ’s E-GMP cars, apart from the high-performance Kia EV6 GT. Its design, value, range, fast charging and other useful tech easily make it one of best electric sedans you can buy.   BMW i4 — $53,195 Though the BMW i4 is essentially an electric version of the 4 Series Gran Coupe, this EV sedan is something special. ItÂ’s packed with power and great driving dynamics in true BMW style. The rear-drive i4 eDrive40 is one quick car, but the i4 M50 is ridiculously fast. If you can get past the questionable nose and the iDrive 8 infotainment system, the i4 is an electric sleeper, and a performance bargain.
